ProComp/Speedmaster aluminum heads

So that's definitely with no question pull the trick flows right out of the box and put them on a gasket and bolt them do with their special bolts. $2500 or so.
$1200 for the Speedmaster fully loaded and CNC'ed.
Problem is which one do you trust to put on right out of the box LOL..
well, technically you need the edelbrock style head bolts/ studs for the speedmasters as well. So both trickflows and Speedmasters need special fasteners.
